Well, it defines a format that can be used to serialize the JSON data
model, but is not specific about corner cases in that data model.

But that is only relevant to ES6 implementations; we don't have to care.

I don't think anybody who cares about use of floating point numbers in
numerics would agree that this representation of -0.0 is "correct".  But
then representing all infinites (all of +Infinity, -Infinity, and NaN)
as "null" doesn't indicate that numerical usefulness was high on the
agenda of the ES6 specifiers.
